The private memory area in vif provided by mac80211 isn't guaranteed to be zeroed. This patch should fix issues when switching between STA and AP interface types. The tim_bitmap could become polluted by STA bssid field (since it's a union), wep_keys array could also become polluted with invalid pointers and probably much more.
